Hello Russell,
this is the pach for the vendor "ODI".
Same hardware but different vendor.
I explained it in the description.
Hope this clarifies.

Thanks and regards

DFP-34X-2C2 is a GPON spf module working at both 1000baseX
and 2500baseX.
Setting the module to LAN_SDS_MODE=6 the module is working
at 2500baseX with auto negotiation see at
https://hack-gpon.org/ont-odi-realtek-dfp-34x-2c2/
Unfortunatly the module's PHY is accessible at 1000baseX only.
ethtool returning:
Supported ports: [ Fibre ]
Supported link modes: 1000baseX/Full

After applying the quirk:
Supported ports: [ Fibre ]
Supported link modes: 1000baseX/Full
2500baseX/Full
Tested on BANANA PI R3 in OpenWRT v 23.05.2 Kernel 5.15.137
Tested on sfp to ethernet Media Converter.
Autonegotiating 1000baseX or 2500baseX according to the
connected host speed.

This module is existing in 2 versions:
Vendor = "ODI"
Vendor = "OEM"
This is the patch for vendor "ODI"

Patch has been inserted keeping the list in alphabetical order
first by vendor first and then by part string.
